Note the german version of this page is a big "portal" related to bicycle mapping

This is a list of suggestions for how to enter and tag bicycle and cycleway related data into OSM. No two cyclists will ever agree what constitutes a good cycle route. Cyclists can seek out anything from only off-road routes to the quickest route on a multi-lane highway. Some want a flat commute, while others seek out hills for a recreational challenge. This is the strength of OSM. It can capture the cycling relevant data as possible, and each cyclist can choose the way that best suits.

Cycle features

Lanes and tracks are represented and tagged differently in OSM. A track is separate from the road (off-road) and a lane lies within the roadway (on-road).
It is recommended[citation needed] by some to draw separate ways if tracks are divided by parking lanes or grass verges, ignoring the track semantics, while others support the intended use of highway=* + cycleway=track (or the more specific cycleway:right=track and cycleway:left=track).

The tables below with many examples and pictures are for right-drive countries.

Cycle lanes in bidirectional motor car roads

A lane marked on a portion of a carriageway (UK), roadway or shoulder (USA), designated for cyclist use.

Way B : assuming for bicycle and buses there is an obligation to use Way A in forward directions (of way A) :highway=*[1] + oneway:bus=yes + oneway:bicycle=yesassuming bicycles may use Way B in both directions :highway=*[1]

B5

Cycle lane shared with a bus/taxi lane on right side of the road (in some countries only).

Where bicycles do not have a legal right-of-way, but the land owner has indicated that bicycles are allowed

bicycle

destination

Where bicycles have a legal right-of-way, but only if their destination is within that street or area

bicycle

dismount

Where cycling is not allowed on short sections of signposted cycleroutes (typically in the UK on narrow bridges and underpasses which are shared with pedestrians), there are usually signs saying "Cyclists dismount". These have been tagged as follows (300+ uses as of 2010-08-15)

oneway:bicycle

yes/no

Instead or in addition to using cycleway=opposite* nominatim, you can use oneway:bicycle to identify roads where the oneway rules for cyclists differ from the generel oneway restriction. Note that currently bicycle:oneway=no and oneway:bicycle=no are both often used and both documented on various places on the wiki. Until there are more certain rules, expect renderers for cycling to support both
